Combined bone grafting: an alternative method for bone healing stimulation

The most provocative problem in bone grafting is the effectiveness of healing of the graft. When you use the heterogenous bone graft, it may take one or more than two years for consolidation and union depends on the graft quality and the situation of surrounding blood supply. In our preliminary report seven cases of freeze-dried heterogenous bone graft from the Bangkok Biomaterial Center were mixed with autogenous iliac bone graft from the patient in the ratio of 3:1. After that the healing was checked by clinical examination and X-ray in the periodic follow up. The causes of bone lost are post evacuation of benign bone tumor and post infection of bone after trauma. The result of bony union could be tested by clinical examination and showed in the X-ray films as early as 3 months post grafting
